4. A lion starts at rest 26 m away from a clueless Jordan and charges towards him at a constant velocity of +50km/h. It takes Jordan 1 s to react to the lion, turn around and begin
running at a velocity of +5 m/s towards his vehicle. Jordan's Land Rover is parked 6 m away
from him and on the same axis as the lion's charge.

a. If Jordan escapes, how far behind him is the lion?
b. If Jordan is caught, how far is he from the Land Rover?

During the apollo moon missions, astronauts were concerned about the effects of newton's third law of motion when: o a. they ejected waste water, because they were concerned that it would push them off course. o b. they reentered earth's atmosphere, because they were carrying heavy moon rocks. o c. they took off from earth, because a large force was required to generate large acceleration. o d. they detected incoming space debris, because the inertia of the debris could damage their ship.
